Network security is the process of taking preventative measures to protect the underlying networking infrastructure from unauthorized access, misuse, malfunction, modification,destruction or improper disclosure.
We live in an age of information. Businesses these days are more digitally advanced than ever, and as technology improves, organizations’ security postures must be enhanced as well. Now, with many devices communicating with each other over wired, wireless, or cellular networks, network security is an important concept. In this article, we will explore what is network security and its key features.
We emulate a malicious attacker attempting to compromise your Mobile or Web Application(s). This enables us to discover any vulnerabilities and/or methods available to maliciously exploit application functions and application infrastructure (providing the scope of the assessment allows). All discovered vulnerabilities are then documented, coupled with remediation techniques (methods of fixing/preventing further exploitation) and then delivered to the client. These are generally an engagement scoped specifically for the client with the client. The client determines what Web Applications they would like assessed.
An in depth analysis of the client's application infrastructure- delivering a report on how to better secure their application suite's infrastructure and all of the information contained therein. This includes but is not limited: to better detection, security-at-rest and overall information storage, information transmission and more. Depending on the scope of the assessment and current infrastructure implemented by the client,what is covered may vary (Databases, Network Setup, Current Application Design, etc.).
An assessment of the client organization's Wireless Network implementation. All discovered vulnerabilities are then documented, coupled with remediation details and techniques (methods offixing/preventing further exploitation) and then delivered to the client.
This is a non-intrusive look at the footprint of an organization. The Silicon Black Group leverages scanning tools developed in-house and externally in order to discover any and all instances of vulnerabilities. Unlike the other assessments, these vulnerabilities are not exploited. This provides the client organization with a baseline as to what their security landscape looks like. All discovered vulnerabilities are then documented, coupled with remediation details and techniques (methods of fixing/preventing further exploitation) and then delivered to the client.
Network security keeps a check on unauthorized access. A network contains a lot of confidential data like personal client data. Anybody who breaks into the network may hamper these sensitive data. So, network security should be there in place to protect them.
Prevent Cyber Attack
Most of the attack on the network comes from the internet. There are hackers who are experts in this and then there are virus attacks. If careless, they can play with a lot of information available in the network. The network security can prevent these attacks from harming the computers.
Levels of Access
The security software gives different levels of access to different users. The authentication of the user is followed by the authorization technique where it is checked whether the user is authorized to access certain resources. You may have seen certain shared documents password protected for security. The software clearly knows which resources are accessible by whom.
Unlike the desktop security software, the network security software is controlled by a central user called network administrator. While the former is prone to worms and virus attacks, the latter can prevent the hackers before they damage anything.
It is very important that the anti-virus software is timely updated. An old version may not offer you enough security against attackers. But it is not guaranteed that every user of the network follows it religiously. A network security system that is centralized offers this advantage of timely updates without even the knowledge of the individuals.
